Power Supply
The power supply for the ProAct II? driver is configured to operate from 20 to 32 Vdc. The minimum current level to be provided by the system will be 6 A dc and 12 A dc for up to two seconds.Actuator Position Feedback
The actuator position feedback output provides a nominal 0.5 to 4.5 Vdc corresponding to 0% to 100% actuator travel. The actuator position feedback will filter the position output signal using a low-pass filter with a cut-off frequency of 40 Hz. The actuator position output has gain and offset adjustments to trim the voltage output for the proper voltages at the correct positions. System Wiring
The actuator driver is capable of driving the actuator through wiring harnesses of the following configurations:The maximum length of the line distance between the battery summed with twice the distance between the control and the actuator must be less than the distance in the following chart. Under no circumstances should the maximum length calculated using the formula above be greater than 16.8 m (55 ft).In applications where these maximum line lengths are followed, the worst case transient current level at elevated actuator temps (100°C ambient) will be 57.5% of the transient limit. This only affects the transient current limits, the steady state limits will still be 6 A.Input Configurations
The following input configurations are available for the position command input. PWMThe PWM input will accept a 1000 100 Hz input signal of 5 to 32 V peak voltage (referenced to unit battery ground). The nominal input of 10% to 90% duty cycle will correspond to 0% to 100% actuator travel (at system calibration temperature). The position command input will be capable of providing a common mode input voltage range (unit battery ground referenced) of 0 to 4 V for all inputs. 0-200 mAThe 0-200 mA input will accept a 0 to 200 mA dc input. The nominal input of 20 to 160 mA will correspond to 0% to 100% actuator travel (at system calibration temperature). The position command input will be capable of providing a common mode input voltage range (unit battery ground referenced) of 0 to 4 V for all inputs. 4-20 mAThe 4-20 mA input will accept a 0 to 20 mA dc input. The nominal input of 4 to 20 mA will correspond to 0% to 100% actuator travel (at system calibration temperature).
